22. Sensors
Graphene sensors
Graphene is an ideal material for sensors. Every atom in
graphene is exposed to its environment allowing it to sense
changes in its surroundings.
Defence
The extreme sensitivity of graphene-based sensors could also
be tuned to chemical warfare agents and explosives. This
could allow for early warning detection systems for soldiers in
the field potentially saving lives.

23. The high structural strength of
graphene makes it an ideal material
to use for manufacturing of
composite materials like aircrafts,
body armor, vehicles etc.

25. Roll to Roll Method
This method was developed in 2011 by Prof. Shou-
En Zhou. He devised a whole new method for
production of Graphene using materials like Argon,
Methane a Copper plate and a furnace which can
reach temperatures of 1000˚C. This method has
overcome three of the most pressing issues
ADVANTAGES
•Low cost
•Less Production Time
•High Quality
•High Scalability
